Why not use a multi-dataset cascaded parameter. Have a look at the
attached example.

Don,
Sorry I posted a 2.5.2 example. Here is an older one.

Maybe I am misunderstanding the issue, but in the example I posted, the
second parameter could have been just one value. It would depend on how
the second dataset is constructed. BTW you can have many more levels.
As far as representing any dataset values on the report that is
definitely doable. You would just use nested datasets, where inner
datasets are fired and passed parameters based on parameters and outer
data set values.

Would nested tables work for you? Take a look at the attached example.
